Frequently Asked Questions
How do I calculate days between two dates?+
Enter the start date and end date. The calculator instantly shows the total number of days between them, plus weeks, months, years, business days, and weekends.
What does include end date mean?+
Include end date counts the final selected date as part of the range. This is helpful when both the first and last day should be included in the total.
Does the calculator count business days?+
Yes. Business days are counted as Monday through Friday. Saturdays and Sundays are counted separately as weekend days.
Are public holidays excluded from business days?+
No. Public holidays are not excluded because they vary by location and organization. Subtract local holidays separately if needed.
Why is the month difference not just total days divided by 30?+
Calendar months have different lengths, so the years-months-days result uses real calendar dates instead of rough averages.
Is this the same as an age calculator?+
No. An age calculator focuses on age from a date of birth. This tool calculates the gap between any two dates for planning, timelines, and schedules.
About this tool
Free Date Difference Calculator
Use the free WebToolsEdge Date Difference Calculator to calculate the time between two calendar dates. Enter a start date and an end date to instantly find the total days between dates, weeks and days, calendar years, months and days, business days, weekend days, and total hours. This date calculator is useful for project timelines, event planning, travel planning, school assignments, contract periods, deadlines, work schedules, and any situation where you need a clear answer to "how many days are between two dates?" Instead of counting manually on a calendar, the tool handles month lengths, year changes, and leap years automatically. The calculator supports an optional Include end date setting. When it is turned off, the result counts the elapsed time from the start date up to the end date. For example, Monday to Tuesday is one day. When Include end date is turned on, the final date is counted as part of the range, which is useful for full-day events, booking periods, assignments, and ranges where both the first and last day matter. Business days are counted as Monday through Friday, while Saturdays and Sundays are counted as weekend days. Public holidays are not removed because holidays vary by country, state, company, and industry. If you need an official workday count, subtract the relevant local holidays from the business-day result. The calendar breakdown shows years, months, and days between the selected dates. This is different from simply dividing total days by 30 or 365 because real calendar months have different lengths. For exact planning, review both the total days and the calendar-style result. All calculations run in your browser. Your selected dates are not uploaded, stored, or sent to a third-party service. The result is designed for practical planning and quick checks; official contracts, payroll, interest calculations, or legal deadlines may use specific rules that should be verified separately.
